Can outside temperature reading be adjusted

Mine is pretty accurate. The only time it's off is when I come out of the car wash - the temp reading can as much as 10 degree lower, but after a couple minutes driving, it's back to normal. You might check with Toyota service next time you're in for maintenance to see if it can be calibrated or re-set to current temps.

 

If you have it in a climate control garage so you know it is 45 degrees and your car has been there for about 12 hours so it can adjust to that temp.. It then should be close in temps.
Now that being said, I do not really know if there is an adjustment to be made but I kind of doubt it.

 

I think so, I recall seeing temperature adjustment in the Carista app. I think it allowed +/- 2 degrees C for the outside temperature and the auto temperature setting.

So you can adjust with the app, get the dealer to do it, or do it using elm327 terminal.

Ah! Good to know, Thanks!

 

The only time my outside temp is off is parking in an open asphalt parking where the sensor is reading the parking lot temps and after a car wash where the sensor gets wet.

As soon as I get moving good the temp will eventually adjust to actual temps. It always agrees with radio and TV temps.

 

So it appears that the answer about "adjusting" it is probably NO.

Maybe you need to make a dealer warranty visit.

But before you do that, as someone else said, I suggest that you park it overnight in a protected area (garage or carport) with a trusted thermometer sitting beside the car.

The next morning if the temp displayed immediately upon starting is off from the thermometer by 5-10 degrees, then I'd say you have a fault that needs to be fixed.

 

Sorry you need the beta version of carista to adjust settings. There is a thread that details how to get the beta version.

Galaxy Nexus ?

 

Hi Lee,

It is one of the customize parameters that can be changed from -3C to +3C. Ask your dealer or anyone with Techstream.



I've changed my Prius c in this thread. The above screenshot is for my c and your ZVW30 may not have the exact same options but the Ambient Temperature Shift should be there.

So grab the pro version. No charge for the pro during the beta.

Nexus 7 ?

 

Hi Frank, thanks for recommending Carista! Yes, Carista definitely supports this customization and as of today, it's fully released (no special beta needed).

Lee, were you able to change the ambient temperature adjustment like you wanted?
